NOTE:The filling of codes and data attributes in the files is specific to summary level; not all fields are filled for every summary level. Where a code or attribute is specified, the actual value is assigned to the field except for the use of three special codes:

Assignment of codes of nine (9) indicates a balance record or that the entity or attribute does not exist for this record.

Assignment of pound signs (#) indicates that more than one value exists for this field and, thus, no specific value can be assigned.

Assignment of exclamation marks (!) indicates that the data are not yet available for this product.

1A unique, six-character identifier for each file series. See "How to Use This Product" for further information.2Identifies the geographic level for which the data matrices on the summary file have been summarized. The summary level sequence chart describes the hierarchical arrangement of the specified geographic areas with other geographic areas, if any. The summary level must be used in combination with the geographic area codes to identify a specific geographic area (for example, summary level 050 and a specific state and county code must be used together to locate the data for a particular county). See "How to Use This Product" for further information.3Indicates an iteration (repetition), for the specified summary level, of the data matrices on the summary file for the geographic components listed in the Geographic Component field. The Redistricting Data Summary File products contain no components. See "How to Use This Product" for further information.

4Indicates an iteration (repetition), for the specified summary level, of the data matrices on the summary file for a population or housing characteristic. These iteration fields apply to Summary File 2 (SF 2) and the American Indian and Alaska Native Summary File only.5The sequence number of the table file within the set of physical files for the state (i.e., the geographic header record file and one or more table files). See "How to Use This Product" for more information.6The logical record is the complete record for a geographic entity defined by the summary level, but exclusive of the characteristic iteration. A logical record may have one or more parts (or segments). Each logical record has an assigned sequential integer number within the file. See "How to Use This Product" for further information.7See Appendix A, "Geographic Terms and Concepts," for definition of this field.8The Federal Information Processing Standards (FIPS) codes were withdrawn as a standard in 2005. The Census Bureau, however, has renamed these codes as Federal Information Processing Series codes and retained the acronym. The two-digit state and congressional district and three-digit county FIPS codes (former FIPS 5, 9, and 6, respectively) are unchanged, but with oversight transferred to the American National Standards Institute (ANSI). The five-digit FIPS 55 codes are no longer a federal code standard; however they are retained in Census Bureau files as administrative codes and used as primary key codes for many geographic entity types. The U.S. Geological Survey has received ANSI oversight for a code standard that uses the Geographic Names Information System identifier (GNIS ID).

The new ANSI standard using the GNIS ID as the official codes for Named Physical and Cultural Geographic Features of the United States and Puerto Rico also is included in Census Bureau files for state, county, county subdivision, place, consolidated city, American Indian area, Alaska Native area, Hawaiian home land, American Indian tribal subdivision, and subminor civil division or equivalent features. The Census Bureau references these fields in the geoheader as ANSI codes and using the term National Standard code. The codes represent the official numeric GNIS ID as an eight-digit character field with leading zeroes. The Census Bureau treats the state and county or equivalent area ANSI codes as supplemental standard codes.

The following lists the published code standards used for the 2010 Census (with its associated Census 2000 standard):

-INCITS.38-200x (R2004), Codes for the Identification of the States, the District of Columbia, Puerto Rico, and the Insular Areas of the United States (Formerly FIPS 5-2)

-INCITS.31-200x (R2007), Codes for the Identification of Counties and Equivalent Areas of the United States, Puerto Rico, and the Insular Areas of the United States (Formerly FIPS 6-4)

-INCITS.454-200x, Codes for the Identification of Metropolitan and Micropolitan Statistical Areas and Related Areas of the United States and Puerto Rico (Formerly FIPS 8-6)

-INCITS 455-200x, Codes for the Identification of Congressional Districts and Equivalent Areas of the United States, Puerto Rico, and the Insular Areas (Formerly FIPS 9-1)

-INCITS 446-2008, (GNIS) Identifying Attributes for Named Physical and Cultural Geographic Features (Except Roads and Highways) of the United States, Its Territories, Outlying Areas, and Freely Associated Areas, and the Waters of the Same to the Limit of the Twelve-Mile Statutory Zone (Formerly FIPS 55-4)

Note: INCITS refers to InterNational Committee for Information Technology Standards.

9 Identifies areas within predetermined population ranges. The actual codes and ranges are common to
all entities with a size code field. The complete list of size codes follows:

The size code fields are not filled for the Redistricting Data Summary File products.

10Codes in unspecified arrangement for U.S. Census Bureau use.11Federal Information Processing Series (FIPS) 55 codes are assigned by state. Because American Indian areas and tribal subdivisions can exist in more than one state, multiple FIPS 55 codes can exist for the entity.12Urban Areas, Urban/Rural classification, ZIP Code Tabulation Areas, and Public Use Microdata Areas are not available in the Redistricting Data products.13Blank values in the Congressional District (111th) field indicate areas where no congressional district was assigned by state redistricting officials.14State legislative district codes have three characters and can include a hyphen (-). The code ZZZ indicates state legislative districts not defined. In the District of Columbia and Nebraska, both of which have a single legislative body, the state legislative districts are reported as upper chamber districts, and the lower chamber districts are coded as 999.15Voting district codes can have one to six characters including special characters of a hyphen (-), dot (.), and forward slash (/). If the code contains less than six characters, the field is right-justified with leading blanks. The code ZZZZZZ indicates voting district not defined in a county or equivalent area containing one or more defined voting districts. A code of six blanks is used in Kentucky, Rhode Island, Oregon (except Multnomah County), and 14 of the 50 counties in Montana, where participants did not define voting districts for entire states or counties.16Land area measurement in square meters. The accuracy of the area measurement is limited by the inaccuracy inherent in the mapping of the various boundary features in the Census Bureau's geographic database. Land area includes areas classified as intermittent water, swamps, and glaciers, which appear on census maps and in the Census Bureau's geographic database as hydrographic features. Square miles can be derived by dividing square meters by 2,589,988. See Appendix A, "Geographic Terms and Concepts," for definition of this field.17Water area measurement in square meters. The accuracy of the area measurement is limited by the inaccuracy inherent in the mapping of the various boundary features in the Census Bureau's geographic database. Water area excludes areas classified as intermittent water, swamps, and glaciers, which are treated as land even though they appear on census maps and in the Census Bureau's geographic database as hydrographic features. Square miles can be derived by dividing square meters by 2,589,988. See Appendix A, "Geographic Terms and Concepts," for definition of this field.18Name of the lowest-level entity represented by the summary level. In addition to the name of the entity, the name field contains the legal/statistical area description (LSAD), when appropriate, and sometimes contains the state abbreviation. For legal entities, the name is the one reported to the U.S. Census Bureau in the Boundary and Annexation Survey or by other appropriate sources, such as state education officials for school districts. For statistical entities, the name is determined by the Office of Management and Budget for metropolitan and micropolitan areas. The remaining statistical area names usually are supplied by tribal, state, or local sources according to published criteria. For redistricting data entities, names are reported by the state redistricting data liaison. For other areas, the name is determined by the local officials, usually in cooperation with the Bureau. When the summary level data represent only part of the area specified in the name, the name usually will have "(part)" appended to the name/code terminology to designate that this entry for the entity represents only a part of the total entity.19The total number of persons enumerated in the specified geographic entity as determined in the 100 percent processing.20The total number of housing units enumerated in the specified geographic entity as determined in the 100 percent processing.21Latitude in degrees, to seven decimal places, of a point within the geographic area represented by the summary level. The character immediately preceding the first digit of the latitude of an internal point identifies the direction (hemisphere): a plus sign (+) indicates the Northern Hemisphere; a minus sign (-) indicates the Southern Hemisphere. See Appendix A, "Geographic Terms and Concepts," for definition of this field.22Longitude in degrees, to seven decimal places, of a point within the geographic area represented by the summary level. The character immediately preceding the first digit of the longitude of an internal point identifies the direction (hemisphere): a plus sign (+) indicates the Eastern hemisphere; a minus sign (-) indicates the Western Hemisphere. A point on the 180th meridian is assigned to the Western Hemisphere (-180.0000000). See Appendix A, "Geographic Terms and Concepts," for definition of this field.23Congressional District (113th), Congressional District (114th), and Congressional District (115th) are reserved for areas established after reapportionment and redistricting.24State Legislative District-Upper and Lower Chamber-for Year 2, 3, and 4 are reserved for areas established after redistricting.
